Jeremy I. Collins, 30, and Holly M. Collins, 28, were charged with one count of child neglect. Both were held without bail Wednesday.

Arrest reports say the child was found outside by a passer-by around 5:30 p.m. The boy was unsupervised for at least 15 minutes and was on a second-floor landing, which put him "at great risk of falling to the first floor, and perilously close to passing vehicular traffic" at a Drew Street apartment complex, the reports said.

A Clearwater police officer said the couple appeared to be confused and "overmedicated and extremely lethargic."

The Collinses told the officer they had prescriptions for Xanax, an anti-anxiety drug, the officer said in the reports.

In addition, the officer found "multiple hazardous items …strewn about the floor" of the apartment, such as power tools.

Pinellas court records show Jeremy Collins was ordered to complete a drug treatment program in 2003 after he admitted to violating his probation on a possession of paraphernalia conviction. Also that year, he pleaded guilty to possession of methadone. Most recently, he was arrested on charges of burglary and resisting arrest without violence in October.

Holly Collins was convicted of driving under the influence in 2008, according to court records.
